The Golden Ratio (1.61) was first described by

>" Euclid (c. 325–c. 265 BCE), in his Elements, gave the first recorded definition of the golden ratio, which he called, as translated into English, "extreme and mean ratio" (Greek: > ακρος και μεσος λογο&#962."
[en.wikipedia.org]

However the structural elements in Egypt seemed to be experimenting with the most striking/pleasant ratios of (width to depth) and (width to height.)

A 4-3 rectangle would be a ratio of 1.33, which many consider the entry range of the Golden Ratio spread. I would think a 4:3 ratio was both impressive and aesthetically balanced with the 3-4-5 triangle not even entering the equation. Please not the Greek records from 2100 years later discuss the 2D rectangles as seen by the eye NOT invisible to the eye circles and triangles.

iirc weren’t there several later tombs and temples that hit the 1.60 ratio pretty closely?
